PCB Order Guideline

We accept single and double-layer PCBs with unlimited vias, pads, and components. The PCB will be printed on a Glass Fiber FR4 board. Our double-layer PCBs that we make don’t have copper plating inside and thus do not provide electrical connection between the top and bottom layers. The customer is supposed to solder wires in the vias to make them conductive.

Like to Inform You:

Creating a PCB is a manufacturing process, so it’ll take several working days for us to print the PCB(s) after receiving your order.
Since PCB is a non-refundable product, you must make an advance payment after verifying your order.
We only print PCBs based on your design. We don’t make PCB designs ourselves for customers.
If you made any errors in your design, we won’t edit it to correct them.
The total days to print your PCB(s) will vary based on the size, quantity, and layer. We’ll inform you about the duration when we call you to verify your order.
